THE INTERACTION OF DISLOCATIONS AND PLANAR FAULTS IN SOLIDS

The equilibrium configurations of an array of straight parallel disloc ations and planar defects bounded by dislocations in a solid are consi dered. On the basis of dimensional arguments and using Euler's theorem for homogeneous functions, it can be shown that the total internal su rface energy of the planar defects is constant for all possible unrest rained equilibrium configurations of the array and is equal to the sum of all pre-logarithmic interaction energy factors.
